In what structure does Windows keep data about what is the working directory (or the current directory) of the process? -

-

while reading on working directory , script directory (or directory contains image of executable file) directories are, started wondering, how windows know, directory pass process working directory, when don't specify working directory when launch given program:

working directory-explicit-implicit-windows

  • through command line, pass location of script directory (~as zeroth parameter). note script directory not working directory.

i know can use getcurrentdir() retrieve working directory inside of program, i'm wondering, windows have 'internal' structure stores working directory of given process? (and if yes, there documentation on structure).

i've found out following process related structures, appears none of them contains working directory property.

the shell (or program launches script), calls createprocess() function. createprocess function has lpcurrentdirectory parameter. shell (or other program launches script), sets lpcurrentdirectory parameter implicitly (~not through parameters of script).

createprocess

that parameter later stored in undocumented property of rtl_user_process_parameters structure. msdnlink, doclink

  • note word: undocumented (that's why haven't found info on msdn in first place).

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
